✦ Synopsis

Laser-schlieren profiles of incident shock waves in 2.5, 5, and 10% C2H 4 in Ar were recorded for the ranges of shock front conditions 2000 < T 2 < 2540°K, 1.8 x 10 -6 < p < 5.4 × 10-6 mol/cm 3. Data analysis was accomplished by computer modeling using a 14-reaction mechanism. Most, but not all, previous observations could be accounted for with the final rate constant set. For C 2 H 4 + M ~ C 2 H 2 + H 2 + M the expression log (k I/cm 3 mol -I s -1 ) = 17.47 -340 kJ/RT, for C2H 4 + M ~ C2H 3 + H + M the expression log (k2/cm3 mol -1 s -1 ) = 17.49 -400 kJ/RT, and for C2H 3 + H ~ C2H 2 + H2 the rate constant k 6 = 1013 cm 3 mol -I s-1 were obtained.
